Going back possibly 15 years here but does anyone remember a cartoon series about the workings of the human body. I'm nearly certain that is was french made but it was definitely in english. It showed kids initially doing what kids do but then once someone had cut their knee (or caught a cold etc) it then went inside the body showing what happened. It would be for young teens or so I reckon as all the proper scientific terms were used and it went into great detail about how the body fights infection etc. I reckon this would be a great tool for my kids as I can remember watching it and being glued to it, given that I was a non-stop outdoors playing football and climbing trees type kid it must have been good to keep me inside.
